Work Sans is a typeface family based loosely on early Grotesques, such as those by <a href="https://www.flickr.com/photos/stewf/14444337254/">Stephenson Blake</a>, <a href="https://archive.org/stream/printingtypespec00millrich#page/226/mode/2up/">Miller &amp; Richard</a> and <a href="https://archive.org/stream/hauptprobeingedr00baue#page/109/mode/1up">Bauerschen Giesserei</a>. 
The Regular weight and others in the middle of the family are optimized for on-screen text usage at medium-sizes (14px-48px) and can also be used in print design.
The fonts closer to the extreme weights are designed more for display use both on the web and in print.
Overall, features are simplified and optimized for screen resolutions; for example, diacritic marks are larger than how they would be in print.
